Prepregnancy body mass index (BMI) of women in United States who gave birth in 2020, by race and Hispanic origin
The Body Mass Index (BMI) "is moderately correlated with direct measures of body fat and is based on weight and height and calculated as kg / m^2."
"BMI values under 18.5 are classified as underweight; those from 18.5 to 24.9 are classified as normal or healthy weight; values from 25.0 to 29.9 are classified as overweight; and values of 30.0 and over are classified as obesity. Within the obesity category, BMI is further divided into three classes. Class I obesity includes BMI values from 30.0 to 34.9, Class II obesity includes values from 35.0 to 39.9, and Class III obesity includes BMI values of 40.0 and over."
